help pls w/ electric baseboard

I have a 220V electric baseboard heater in a bathroom. It is properly sized for the room but barely produces any heat. I opened up the wiring panel and found only 3 wires coming in, so I thought the previous owner had mistakenly wired a 220V heater to a 110 line and ordered a new 110V heater.

Today I remove the old heater to replace it and discover what I think is a 220 line coming out of the wall, pigtailed to to the heater. Out of the wall there is red, black, white and ground. Black, white and ground are pigtailed to the heater, and red is capped off.

If I am understanding correctly, the black & red are the supply lines and should be connected to the heater, while the white (neutral) should be capped off. Am I right?

The wires attached at the heater need to match the wires attached to the breaker.

A 240 volt baseboard does not need the neutral wire. this is why 2 wire with ground cable is used. The white is just color coded as a hot conductor. You could do as you suggested and use the red for the heater and cap off the white.
